It's time to try the upgrade to Audi Sound System PR-9VD. If your car has Passive Speakers PR-8RX, you must install a center speaker, a factory sub woofer which goes to the boot into the spare wheel and replace the front door speakers to other with different resistance. On Ebay, you can find all parts for about 90GBP shipped, worths the upgrade</font>
</font>Part numbers are below:</font>
</font>Center speaker:8X0035416C</font>Subwoofer:8U0035382</font>Front door speakers:8R0035415A</font>Subwoofer connector:1J0972923</font></font>Center speaker connector:</font>1J0971972</font></font>
</font>Then you must enable ASS on the RMC, I did it using VAG CAN Pro cable and activated ok. Connection must be done according to the picture below:</font>
</font>
</font>
</font>
</font>Haven't finished the mod, because I'm waiting for the parts, but all is done including the wiring, so will post when finished to tell you about sound quality.</font>
